The network communication technologies may facilitate people to communicate with each other more efficiently and free people from the limitation of space and time. By the technology and environment of network communication, multimedia information (e.g. texts, sound, pictures and images) could be transmitted in an interactive manner. Recently, the optical communication system gradually replaces the electronic communication system in order to increase the communicating speed and quality of Internet. Optical fiber is the most common data transmitting medium of the optical communication system because it advantageous for low loss, high bandwidth, no potential electromagnetic interference problem, light in weight, and good security. As such, the optical fiber communication system has experienced great growth and is now rapidly gaining in popularity.

As such, the network transmission speed of eachuser terminal 11 is enhanced. - Since the
network device 112 of eachuser terminal 11 is powered by thepower source 113 that is provided by a power company, if the electricity provided by thepower source 113 is subject to a sudden variation or interruption, the networking resource fails to be normally provided and a data damage problem is possibly incurred.

In this embodiment, the networkphysical transmission unit 41 is an optical fiber communication equipment converter such as a hub, a switch, an IP sharer or a router.

communication connecting ports 413 are connected withrespective computers 51 at the user terminal. Alternatively, thecommunication connecting port 413 could be connected with an IP Phone. The telephone connecting port 414 is connected with atelephone 52 at the user terminal. An example of thetelephone 52 is an ordinary indoor telephone. - Hereinafter, two approaches of connecting the user terminal and the
optical line termination 6 through the networkphysical transmission unit 41 of thenetwork device 4 according to the present invention will be illustrated with reference toFIG. 3 . It is noted that, however, those skilled in the art will readily observe that numerous modifications and alterations may be made while retaining the teachings of the invention. - In a first connecting approach, the
optical communication port 411 is directly in communication with the network equipment of theoptical line termination 6 through anoptical fiber 61. This approach can be referred as a fiber to the home (FTTH) technology. Through theoptical communication port 411, an optical communication signal from the network equipment of theoptical line termination 6 is received by the networkphysical transmission unit 41, and then the optical communication signal is transmitted to the opto-electronic convertingelement 415. Alternatively, an optical communication signal is transmitted from the opto-electronic convertingelement 415 to theoptical communication port 411, and then transmitted to the network equipment of theoptical line termination 6. As such, the data packets in an electronic communication form could be transmitted from thecomputers 51 at the user terminal to the networkphysical transmission unit 41 through thecommunication connecting ports 413, then the data packets in the electronic communication form are converted into data packets in an optical communication form by the opto-electronic convertingelement 415, and finally the data packets in the optical communication form are transmitted to the network equipment of theoptical line termination 6 through theoptical communication port 411 and theoptical fiber 61. - On the other hand, the data packets in the optical communication form could be transmitted from the network equipment of the
optical line termination 6 to the networkphysical transmission unit 41 through theoptical fiber 61 and theoptical communication port 411, then the data packets in the optical communication form are converted into the data packets in the electronic communication form by the opto-electronic convertingelement 415, and finally the data packets in the electronic communication form are transmitted to thecomputers 51 at the user terminal through thecommunication connecting ports 413. - In a second connecting approach, the
electric communication port 412 is in communication with thenetwork switch 7 through atelephone cable 62, and then the network switch 7 (which is installed within the community building by the optical line termination 6) is in communication with the network equipment of theoptical line termination 6 through anoptical fiber 61. This approach can be referred as a fiber to the building (FTTB) technology. Through theelectric communication port 412, an electronic communication signal from thenetwork switch 7 is received by the networkphysical transmission unit 41, and then the electronic communication signal is transmitted to thecircuit board 417. Alternatively, the electronic communication signal from thecircuit board 417 is received by theelectric communication port 412, and then transmitted from theelectric communication port 412 to thenetwork switch 7. The data packets to be transmitted between the user terminal and thenetwork switch 7 are both in the electronic communication form. - In other words, when a user at the user terminal intends to communicate with another user at the Internet side through the
telephone 52 connected with the networkphysical transmission unit 41, the voice signal is firstly transmitted to the networkphysical transmission unit 41 through the telephone connecting port 414. Then, the voice signal is converted into the data packet in the electronic communication form by theVoIP phone chip 416. Afterwards, the voice signal of the user at the user terminal is transmitted to another user by the first connecting approach or the second connecting approach described above. Similarly, the voice signal of another user at the Internet side may be transmitted to the user at the user terminal in the same manner, so that the purpose of communication via voice is achieved. - Hereinafter, the key features of the present invention will be illustrated with reference to
FIG. 4. FIG. 4 is a schematic functional block diagram illustrating an exemplary network device ofFIG. 2 , in which the detailed configurations of the backup power supply module are shown. As shown inFIG 4 , the backuppower supply module 42 comprises acharger 421 and abattery set 422. In a case that electricity provided by theexternal power source 8 to thenetwork device 4 is normal, thecharger 421 also receives the electricity provided by theexternal power source 8 to charge the battery set 422, so that the battery set 422 is in an electricity saturation status. Whereas, in a case that theexternal power source 8 fails to normally provide the electricity, the battery set 422 will immediately provide backup electricity to the networkphysical transmission unit 41. - Therefore, before the electricity quantity stored in the battery set 422 is exhausted, the user at the user terminal may take emergency measures to operating tasks at hand, such as data storing. At the same time, the
network management module 44 may detect the electricity quantity stored in the battery set 422, and transmit the information associated with the electricity quantity to the user at the user terminal. According to the information associated with the electricity quantity, the user at the user terminal could take measures. For example, while the user at the user terminal uses an IP phone to perform voice communication, the user may adjust the talking period according to the importance of talking contents. - In the above embodiments, the function of the backup
power supply module 42 is exhibited if the electricity provided by theexternal power source 8 is subject to a sudden variation or interruption. It is noted that, however, those skilled in the art will readily observe that, if the power quality is reduced because of surge, sharp wave, noise, power sag or high (low) voltage transient, the backuppower supply module 42 can automatically stabilize the voltage. In this situation, stable and reliable electricity will be continuously received by the network device. - While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
